To all whom it may concern:

Be it known that I, EMIL GUNDELACH, a citizen of the United States, and a resident of the city of New York borough of Manhattan, in the county and State of New York, have invented a new and Improved Carbureter, of which the following is a full, clear; .and exact description.-

The invention relates to explosion motors or engines for automobiles and the like, and its object is tov provide a new and improved carbureter which is simple and durable in construction, and arranged to insure an in :timate mixture of the air and gas, to force a to or outlet section A engine, so that whe improvement; Fig. 2 is a plan the explosive mixture thus formed into the workin chamber ofgthe motor under pressure, with a view toforcibly drive outth'e residual matter left by a revious explosion, and to fill the working c amber with an efficient fuel charge even when running the motor at a high rate of speed. i

The invention consists of novehfeatures and parts and combinations, of the same, which will be more fully described hereinafterand then pointed out in the claims;

A practical embodiment of the invention is represented in the accompanying drawings forming a part ofthis specification, in

which; a

Figure 1 is a sectional side elevation of the 'view of the lower section of the casing, parts being shown in section; and Fig. 3 is a plan view of the throttle valve, on the line 3-3 of Fi 1. I i

Fhe casing or shell A} of the carbureter consists preferably of a central section A, connected with the 'ngchamber of the'motor or en ine, ottom section A rovided wit an 'Wor and a inlet-A coupled by a pipe end=C' ofa an or blower C oilany ap roved construction. The shaft C of the w eelC of the fan or blower C, is provided. with a pinion D in mesh with an apertured band Di secured on the fl heel E of the motor or 1e latter is in operathe tion a rotary motion-is transmitted to wheel C of the fan or blower C,- to force air through the outlet C and the-inlet A into the bottom section A of-the shell or casing A5 -I have illustrated and describeda sim le the wheel (3 of the an means for runnin or blower C, but 1t is evident that I dot'not limit myself to the particular construction to the discharge shown and. described, as other suitableimeans may be employed, for the wheel 0 from' the motor or'engme' Other suitable means may also ,be employed for delivering a blast of air to thebottorn section A of the casing. A, itb eing understood however, that such meansyare-'located'outside of the casing A and are independent thereof.

. The inlet A 1s provided with a valve seat A engaged by a valveF mounted to slide loosely on avalve stem F and ressed to its seat by a s ring G coiled on t e said valve stem F an resting at one end on the valve F and at the other end on a loop or shoulder F formed on the valve stem-F. The valve stem F extends in the bottom section A and is provided near itsouter end wit'h'an annular groove F engaged loosely b a'shifting screw H screwing in a split nut H attached to the bottom section A? and. extending to the outside thereof. On the outer tapering and externally threaded end of the nut H screws a correspondinglfi sha ed nut H, for securely clamping t e shi ting screw Hin place. Now when the nut H is loosened the screw H can be screwedinward or outward from the outside of the casing A, to shift the stem F in the direction of its length, thus increasing or decreasing the tension of the spring (3 tohold the valve F with more or less force against its seat A and against the air blast from the fan or blower C. After the tension of the spring G is regulated, the nut H isscrewed' u to securely clamp the screw in place. 7 he valve F is rovided with one or more apertures F to a ow some 'of the air blast to pass. through the valve F into the casing A even if the valve F is in a seated or closed position, .it being, however, understood that the'valve F opens as soon as the pressure of the air blast evercomes the tension of the sprin -G.= The bottom section 8 connects with .the

inlet I of a mixing chamber I contained in' being arranged in the lower portion of the central section A of the shell or casing. A; A supply pipe connected with a suitable "gasolene or like liquid fuel supply discharges inlet I containing the spraying device K.

Thenozzle K of" the s raying device K is held on the upper end 0 a tube K contained within the pipe K and held lengthwise adjustable therein, to bring the nozzle K closer-to or farther from the upper outlet end liquid of the ipeK to control the spraying of the i uel. The tube K is provided with openings K opening into the pipe K, so as to a low sediment, water or the like contained in the gasolene to pass into the tube K to be discharged from the lower end thereof from time to time on opening a suitable valve R.

The pipe K is secured to and forms part of the middle section A and its lower end forms a bearing for the lower section A of the casing A to turn on, with a view to bring the inlet A into the b ower or fan 0. -When the desired adj ustsurrounding ment is made a nut K is screwed up on the lower threaded end of the pipe K and against the underside of the bottom of the section A, to secure the sections A and A in place. A nut K serves to lock the tube K in place in the pi e K after the nozzle K properly adjuste The pipe K extends through the loop F of the valve stem F to hold the latter against turning. The top section A? is provided with oneor more outlets A and is held rotatable on the middle section A, to allow of bringing the outlets in proper alinement.

with the working chamber of the engine. The sections A and A are secured togetherafter the pro er adjustment is made, by bolts A as plalnly indicated in Figs. 1 and 3.

In order to heat the mixing chamber I, the exhaust is conducted into the s ace S the mixing chamber I in the upper portion of the central section A the latter being provided with a nipple A for connection with the exhaust of the motor or engine. 1 An outlet opening A in the central section A permits the escape of some of the exhaust passing into the space S.

The operation is as follows: When the motor or engine is running a rotary motion is given to the wheel C", for the latter to force air under pressure through the inlet A into the bottom section A from which the'air blast passes up through the inlet'I to spray the liquid fuel at the nozzle K of the spraying device K. The air under pressure roper alinement with the outlet 0 of and the sprayed gasolene are now intimately mixed in the mixing chamber I, and the resultant mixture passes under pressure through the outlet section A into the working chamber of the motor or engine, so as to drive out any residual matter left by a previous explosion in the said workingchamber, and at' the same time the working chamber is com- .pletely filled with an explosive charge no matter at what rate of speed the engine or motor is running. It is understood that according to' thee eed of the motor or engine the pressure of t e air blast increases or decreases correspondingly, and, consequently, when the motor or engine 18 running at ahigh rate of speed the pressure mc'reases'and, consequently, the explosive mixtureis forced in a fraction of a second under high pressure dependedupon to fill the working chamber with an explosive charge, but the latter is er pressure into the working forced un or engine is chamber as soon as the piston is on the suction stroke.

The gasolene issues into the mixing chamber, which is connected directly with "the reservoir. The tube K is completely closed at'its top and is adjustable in the tube K,

to move the'nozzle K? toward or from the open end of the tube K to control the amount of liquid issuing from the tube K. The lower end of the tube K is open, and openings K provide a communication between the said tube and the tube K so that sediment or water from the gasolene may pass into the tube K and be discharged therefrom on opening the valve R. f

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
